The logistics are the same as with CBaseServer, if someone with a reserve slot connects while the server is full (using the connect console command), someone who doesn't have a reserve slot is kicked. No "holding" slots are needed, and many people can try to connect at once.

There aren't any reserved slot plugins using this extension yet, but it would be trivial to take one designed for CBaseServer, change the include and function prototype and recompile it.
